# `inky_to_html`

New in version 2.12: The `inky_to_html` filter was added in Twig 2.12.

The `inky_to_html` filter processes an inky email template:

    {% apply inky_to_html %}
        <row>
            <columns large="6"></columns>
            <columns large="6"></columns>
        </row>
    {% endapply %}

You can also use the filter on an included file:

    {{ include('some_template.inky.twig')|inky_to_html }}

Note

The `inky_to_html` filter is part of the `InkyExtension` which is not installed by default. Install it first:

    $ composer req twig/inky-extra

Then, use the `twig/extra-bundle` on Symfony projects or add the extension explictly on the Twig environment:

    use Twig\Extra\Inky\InkyExtension;

    $twig = new \Twig\Environment(...);
    $twig->addExtension(new InkyExtension());
